Sample audit report output
Image SEO score: 31 / 100. Fix all issues automatically?
Fix with ImageSEOSeven signals that determine how Google ranks your images — all checked in one scan.
Percentage of images with descriptive alt attributes. Missing alt text is the single biggest image SEO issue — Google cannot index images without it.
Generic filenames like IMG_0001.jpg pass zero keyword signal to Google. The audit scores each filename against descriptiveness and keyword relevance.
WebP images are 25-35% smaller than JPEG at equal quality. Lower file size means faster LCP which is a direct Core Web Vital ranking factor.
Images that load eagerly below the fold block the browser and increase LCP. The audit identifies every image missing the loading=”lazy” attribute.
Schema markup on images enables rich results in Google Images and improves entity understanding. Almost no sites implement this — giving you a competitive edge.
On multilingual sites, images should be correctly attributed to the right language cluster. The audit flags image URLs that break hreflang signal chains.
404 images hurt both UX and crawl budget. The audit catches every broken src attribute across all scanned pages.
Run a full image SEO audit on any client site in minutes. Export the PDF report, present the findings, then fix everything automatically with ImageSEO. Charges justify themselves on the first client.
Product catalogs with thousands of images are the highest-risk sites for image SEO debt. The audit shows exactly how many product images are invisible to Google and what it costs in traffic.
Sites where images are the content, not just decoration. A photographer or stock agency with 50,000 un-optimised images is leaving their entire catalogue out of Google Image Search.
Use the audit as a quarterly health check. Track alt text coverage, WebP adoption rate, and schema markup implementation over time to demonstrate progress to stakeholders.

The score is a weighted average across seven signals: alt text coverage (30%), file naming quality (20%), WebP adoption (15%), lazy-load rate (15%), structured data presence (10%), hreflang consistency (5%), and broken URL rate (5%). Each signal is scored 0-100 and the weighted total gives your overall image SEO score.
Yes. The free audit works on any URL without installation. For agency workflows, ImageSEO agency plans allow white-label PDF report exports, multiple client workspaces, and bulk audit scheduling across all client sites in a single dashboard.
General crawlers check whether alt text exists (present or missing). ImageSEO goes deeper: it scores the quality of existing alt text for keyword relevance, checks file naming descriptiveness using computer vision, identifies WebP conversion opportunities per-image, and verifies structured data implementation. It is purpose-built for image SEO rather than general on-page auditing.
The audit report links directly to ImageSEO workflows for each issue type. Alt text: 1-click AI generation for all flagged images. File names: bulk rename with keyword-based suggestions. WebP: automatic conversion and re-upload to your media library. Each fix category has a dedicated workflow that processes images in batches without manual effort.
Yes, and it is especially valuable for WooCommerce. Product images, gallery images, and variation images are all crawled. The report segments results by product category so you can see which parts of your catalogue have the worst image SEO health and prioritise fixes by revenue impact.
